CATCH-BASIN.

T 0 all whom it may concern:

Be it known that I, FRANK L. UNION, a citizen of the United States, residing at New York, borough of Manhattan, county and State of New York, have invented certain new and useful Improvements in Catch Basins, of which the following is a specification.

My invention relates to catch basins or receiving basins which are usually located at street corners or at the street curb for receiving sewer water, usually caused by mm.

The main object of the invention is to prevent clogging up of the outlet pipes of catch basins by mud and other obstructions and to preferably compel a complete cleanout of the catch basin whenever suflicient mud has accumulated to prevent normal op eration of the basin.

Under the present invention it will be obvious to those having charge of the sewers of a town that the basin has been filled with as much mud as it will bear when the water begins to back out from the catch basin on to the street. It is then time to clean out the basin so that it will operate in the desired manner.

Other objects are to provide a practical and efficient catch basin.

\Vith these ends in view, my invention consists of certain features of construction and combinations of parts to be hereinafter described, and then particularly claimed with reference to the accompanying drawings showing a desirable form of the invention, and in which- Figure 1 is a central vertical section of a catch basin provided with my improvements; Fig. 2 is a transverse section thereof on the line 22, Fig. 1; and Fig. 3 is a detail perspective view of the outlet means which dips into the basin and discharges the water which enters the basin.

The form of catch basin shown in the drawings is cylindrical, but it may obviously be rectangular or any other shape, as the constructing engineer may consider desirable. In the drawings the catch basin is shown as comprising the usual receiving chamber or well 1, which is constructed of masonry or brick-work, and above which is the side-walk top slab 2 provided with the usual manhole and cover 3, together with an inlet mouth 1, in which may be located a guard 5 and behind it a shield or apron 6 Specification of Letters Patent.

which is directly below the slab or top 2. These are the parts of the usual catch basin, and may be changed at pleasure.

The receiving chamber 1 of the catch basin has located therein a partition 7 which extends upwardly from the floor of the receiving chamber, preferably to a level with the outlet sewer pipe 8. Said partition 7 divides the chamber 1 into a main mudtrap 9 and a supplemental mud-trap 10, the main mud trap being located at the front of the chamber and the other and smaller trap at the back. Partition 7 is preferably arched in horizontal cross-section as shown in Fig. 2, the arch extending toward the main mudtrap 9 so' as to be capable of withstanding the greater pressure in that part of the catch basin. The opposite edges of the partition are preferably embedded in the masonry or brickwork of chamber 1 as indicated at 7 7 Fig. 2. At the lower end of the partition 7 is a preferably wide opening 11 eX- tending to the floor of chamber 1, and kept usually closed by means of a valve or door 12 preferably guided in a vertical direction by guides 1313 at opposite sides of the partition. Said opening 11 constitutes a clean-out opening to permit the mud accu mulated in mud trap 10 to be removed.

The main feature of the present invention resides in outlet means which dips into the supplemental mud-trap 10, said means preferably consisting of an elbow pipe 141 with a short connecting leg 15 and a longer leg 16. The short leg 15 is joined to the outlet sewer pipe 8, and the longer leg 16 depends or dips into the supplemental mud-trap 10 and runs a considerable distance down into said trap, so that its lower inlet end will be located a short distance above the clean-out opening 11. Located in the bend of the pipe 11 is an opening 17 controlled by a re lief valve 18, preferably having a hinge connection at 19 between its upper edge and the pipe 14 so that the said valve will close by its own weight. Said valve is preferably inclined and is located so far in advance of the rear wall of the chamber 1 that it may be swung upwardly and against said rear wall, where it remains until it is pulled down again. For opening the relief valve 18, the same is preferably provided at its lower free end with an eye 20 to which is attached a pull chain or connection 21 which is preferably attached at its upper end to an eye 22 in the top slab 2 of the receiving chamber 1. The upper end of the chain is preferably secured at a point immediately back of the manhole of the top 2, so that one may reach in through the manhole and pull the chain when required. It will be observed that the height of the partition 7 is such that a large opening 23 is formed in the receiving chamber between the upper edge of the said partition and the bottom of the top slab 2. The lower part of this opening is preferably located on a level above the level of the lower part of the valve controlled opening 17, while the opening 17 is preferably in line with the sewer pipe 8, as clearly indicated in Fig. 1.

My improved catch basin is operated and used as follows :During a heavy rainfall the main mud-trap 9 may or may not become filled with mud, the water entering the inlet opening 4 and into the chamber 1, flowing over the partition 7 and down into the supplemental mud-trap 10 from whence the water flows upwardly through the outlet means or pipe 14 into the sewer pipe 8. It will be observed that the location and the arrangement of the opening 17 and relief valve 18 are such that the valve is pressed tightly against its seat by the weight of the inrushing water. hen the main mud-trap 9 is filling with mud as indicated, mud accu mulates more or less rapidly in the supplemental mnd-trap 10, and as long as the pipe 14 is not clogged up, the sewer water will flow up through said pipe and out through the sewer pipe. After a time the mud accumulates in the supplemental mud-trap 10 to such a height and in the lower end of the pipe 14 to such an extent that the latter becomes clogged up and no more water can flow into the sewer pipe. Then the catch basin fills up with water and it backs out on to the street, thereby indicating to those having charge of the sewer that it is time to open the relief valve 18. When this has been opened, the water entering the catch basin will flow through the relief opening 17 and into the sewer pipe 8. At the proper time the valve 18 is returned to a closed position, and the catch basin cleaned out. First the mud in the main trap 9 is removed and then the door or valve 12 is opened so that access may be had into the supplemental mud trap 10 by means ofa shovel. The mud in the latter is then gradually removed and that in the lower end of the pipe 14 falls out and leaves the pipe clear. After the trap 10 has been cleaned, the door or valve 12 is closed and the catch basin is then in best condition for operation.

It will be clear from my invention that the usual obstruction of the sewer pipe 8 is avoided and that very little mud enters the same. In fact, practically all of the mud is intercepted in the catch basin and may be removed so that the expense of taking care of catch basins is lessened, and the possible expense of opening up the sewer pipe as by digging up the street avoided.

Obviously the various parts may be composed partly of metal and masonry or earthenware, or wholly of either of them.

What I claim as new is:

1. In a catch basin, the combination of a chamber, provided with an inlet-mouth, a partition in said chamber, back of said mouth, and an outlet pipe extending downwardly into the space behind said partition, said outlet pipe having a valvecontrolled relief opening located at the approximate level of the upper edge of said partition.

2. In a catch basin, the combination of a chamber, provided with an inlet-mouth, a partition in said chamber, back of said mouth, and an outlet pipe extending downwardly into the space behind said partition, said outlet pipe having a valve-controlled relief opening located at the approximate level of the upper edge of said partition and said partition having a controlled clean-out opening.

3. In a catch basin, the combination of a chamber, provided with an inlet-mouth, a partition in said chamber, back of said mouth, and an outlet pipe extending down wardly into the space behind said partition, said outlet pipe having a valve-controlled relief opening located at the approximate level of the upper edge of said partition and means for operating the valve of said relief opening.

41-. In a catch basin, the combination of a receiving chamber, a partition dividing said chamber into a main mud-trap and a supplemental mud-trap at opposite sides, with outlet means dipping into the supplemental mud-trap and means for admitting water to said outlet means at a point above the lower inlet end of said outlet means when the said inlet end is clogged up.

5. In a catch basin, the combination of a receiving chamber, a partition dividing said chamber into a main mud-trap and a supplemental mud-trap at opposite sides, with outlet means dipping into the supplemental mud-trap, means for admitting water to said outlet means at a point above the lower inlet end of said outlet means when the said inlet end is clogged up and means to permit said supplemental trap to be cleaned out.
